This invention concerns a gas spring having a working cylinder (10) and therein a slidably arranged piston (2), whereas the working gas is, in order to provide for springing and dampening, optionally transferable between the working cylinder (10) and the reservoir (20), characterized in that the reservoir (20) is arranged in the piston rod. The gas or air spring according to this invention is self- dampening in both directions, i.e. at compression as well as at the extension. At compression it behaves as an air spring with dampening and at the extension it also behaves as an air spring with dampening, whereas both these damping effects can be, as regards the magnitude of the dampening, controlled independently from each other. |
